4 Claims. (Cl. 5-174) This invention relates to an improved folding bed frame, and in particular it relates to a bed frame which is provided with corner braces on the foot end rail which engage the side rail to prevent twisting strain on the pivotal connections between the end rail and the side rails.

The principal object of the invention is to provide a simple and inexpensive corner brace which is mounted upon the end rail adjacent its pivotal connection with the side rail, and which engages the side rail automatically when the end rail is pivoted to its bed frame forming position pe-rpendicular to the side rail.

A further object of the invention is to provide a corner brace which may be formed from at metal stock in conventional punching and bending operations.

Yet another object of the invention is to provide a corner brace which has no moving parts and which not only braces the corner but also stops the movement of the end rail when it is perpendicular to the side rail.

The invention is illustrated in the accompanying drawings in which:

Fig. 1 is a plan view of a folding bed fra-me equipped with the corner brace of this invention;

Fig. 2 is a fragmentary end elevational view on an enlarged scale;

Fig. 3 is a fragmentary plan view on an enlarged scale of one corner of a bed frame provided with the corner brace of the present invention;

Fig. 4 is a section taken as indicated `along the line 4 4 of Fig. 3;

Fig. 5 is a fragmentary end elevational View of the device; and

Fig. 6 is a section taken along the line 6-6 of Fig. 5.

Referring to the drawings in greater detail, a bed frame has side rails 10 each of which is an angle iron with a rst ange 11 extending horizontally inwardly and a second flange 12 extending vertically so that a box spring may be supported on the horizontal flanges and conined against lateral movement 'by the vertical flanges.

The frame includes a head end rail, indicated generally at 13, consisting two angle members 13a and 13b which are pvotally mounted on top of side rails 1h with a leg extending up, and bolted together at 13C. The head end rail has conventional corner braces 13d. The frame also has a foot end rail 14 which consists of `an angle iron 15 which, as best seen in Figs. 2, 3 and 5, is mounted on a heavy pivot 16 in spaced relation to the foot end 17 of the right hand side rail 10, the angle iron 15 having a horizontal leg 18 which is beneath the horizontal flange 11 of the side rail and is spaced therefrom by a large washer 19, and a depending leg 20. The pivot 16 may conveniently be a pin having large heads at 'both ends. Rigidly secured to the angle iron 15 inwardly of the side rail 10 is a leg 21 provided with a caster 22. A second angle member 23 is secured to the left hand side rail 10 by means of a pivot 24 and is adapted to overlap the angle member 15 so that they may `be secured together as by 70 means of -bolts 25.

ice

A headboard 26 is bolted to the head end rail 13 and to the two side rails as seen in Fig. l.

Referring particularly now to Figs. 3 6, inclusive, the foot end rail 14 is provided adjacent each of the pivots 16 and 24 with a corner brace indicated generally at 27, which is the subject of the present invention. The corner grace 27 is an inverted U-shaped bracket with one arm 28 of the U serving as an attaching arm which is rigidly secured to the depending leg Ztl of the angle member 15 by means of bolts and nuts 29. The base 39 of the U-shaped bracket serves as a bracing arm, and the bracket also has a depending outer arm 3l which is parallel to the attaching arm 28. As best seen in Fig. 5, the corner brace is mounted in an inclined position, and the bracing arm 3@ has a horizontal forwardly extending flange gripping portion 32 which projects slightly beyond the upright arms 2S and 3l of the corner brace and has its lower face 33 aligned with the top face 34 of the horizontal flange 11 of the side rail. A pair of aligned horizontal slots 35 and 36 are formed in the corner brace at the juncture of the ange gripping portion 32 and the upright arms 2S and 31. Thus, `as best seen in Fig. 5, when the end angle member 15 is swung on the pivot 16 to a position normal to the side rail 19, the horizontal flange 11 of the side rail enters the slots 35 and 36 and the flange 11 is rmly gripped between the flange gripping portion 32 and the tops 37 and 3S of the upright arms of the brace which form the lower margins of the slots 35 and 36. The position of the corner brace 27 is such that when the `end rail angle member 15 is normal to the side rail 10 the edge of the horizontal flange 11 of the side rail is bottomed in the slots 35 and 36 so that proper positioning of the end rail and side rails is assured.

The foregoing detailed description is given for clearness of understanding only and no unnecessary limitations are to be understood therefrom, as some modications will be yobvious to those skilled in the art.

I claim:

1. In a bed frame having a side rail consisting of an angle iron with a horizontal, inwardly extending ilange and an end rail consisting of an angle iron pvotally mounted beneath and in spaced relation to said inwardly extending iiange adjacent an end of said side rail, said end rail having a depending leg, a corner brace comprising: a bracket having an attaching -arm rigidly secured in face abutting relationship to the outside `of the depending leg of the end rail and an integral horizontal bracing arm the lower face of which is aligned with the top face of the horizontal flange of the side rail, said bracket having a horizontal slot at the juncture of the attaching arm vand bracing arm and being so positioned that when said end rail is pivoted to a position normal to said side rail said slot receives a marginal portion of the horizontal ilange and said flange is gripped between the attaching arm and the bracing arm.

2. The device of claim l in which the bracket is an inverted U `one of the upright arms of which forms the attaching arm, and there is a slot at the juncture of the bracing arm and the other arm of the U which is aligned with the slot at the juncture of the attaching arm yand the` bracing arm.

3. The device of claim 2 in which the bracket is mounted in an inclined position, and only the ilange gripping portion of the bracing arm is horizontal.

4. The device of claim l in which the bracket is so positioned that the edge of the horizontal ange bottoms in the slot when the end rail is normal to the side rail.
